protected from unauthorized manipulation. If the LAN is to be connected to an outside network, no unautho-
rized attempt to establish connection from the external network should be permitted.

-If the LAN, in which the machine is installed, is connected to an outside network, install a firewall or 
similar network device to block any access to the machine from the outside network and make the nec-
essary settings.
-Configure the LAN installed in the office, in which the machine is installed, by using a switching hub and 
other devices to ensure that the packets are protected from unauthorized manipulation.
-Provide an appropriate network control at all times to make sure that packets are protected from un-
authorized manipulation and no other copying machine is connected without prior notice to the office 
LAN to which this machine is connected.
User information control server control requirements
The server administrator is required to apply patches and control accounts for the user information control 
server connected to the LAN within the office, in which this machine is installed, to ensure operation control 
that achieves appropriate access control.
Security function operation setting operating requirements
The Administrator should make sure of correct operation control so that the machine is used with the En-
hanced Security Mode set to [ON].
Operation and control of the machine
The Administrator of the machine should perform the following operation control.
-The Administrator of the machine should log off from the Administrator Settings whenever the operation 
in the Administrator Settings is completed. The Administrator of the machine should also make sure 
that each individual user logs off from the User Authentication mode after the operation in the User Au-
thentication mode is completed, including operation of the Secure Print Document, User Box, and User 
Box file.
-The Administrator of the machine should set the Encryption Key according to the environment, in which 
this machine is used.

Password Rules
According to certain Password Rules, registration of a password consisting of a string of a single character 
or change of a password to one consisting of a string of a single character is rejected for the Administrator 
Password, User Password, Account Password, User Box Password, Secure Print Password, SNMP Pass-
word, WebDAV Server Password, and Encryption Key. For the Administrator Password, User Password, Ac-
count Password, User Box Password, SNMP Password, WebDAV Server Password, and Encryption Key, the 
same password as that currently set is not accepted.
Study the following table for details of the number of digits and characters that can be used for each pass-
word.
Precautions for Use of Umlaut
-The maximum number of digits allowed for the User Password is 64, if umlaut is used with all charac-
ters, however, the maximum number of digits allowed becomes 32 digits.
-Setting or entering an umlaut from the control panel may be disabled depending on the setting made 
in this machine, but not on the client PC side including PageScope Web Connection. If an umlaut is set 
in a password on the PC side, therefore, the umlaut cannot be entered from the control panel, which 
means that this particular password is not usable.
Precautions for Use of Various Types of Applications
Comply with the following requirements when using various types of applications.
-When PageScope Web Connection or an application of various other types is used, the password con-
trol function of the application stores the password that has been entered in your PC. If you want the 
password not stored, disable the password control function of the application. 
When using the PageScope Web Connection or an application of various other types, use one that 
shows * or ● for the password entered.
-Internet Explorer or other type of web browser, SSL v3 or TLS v1 should be used, not SSL v2, for 
the SSL setting.
-Expanded functions, which can be used in association with applications by registering the optional Li-
cense Kit, are available, including collecting and controlling user and account information by means of 
the WebDAV function. Use of these expanded functions is not covered by certification of ISO15408.

Encrypting communications
The following are the cryptographic algorithms of key exchange and communications encryption systems 
supported in generation of encryption keys.
-TLS_RSA_WITH_RC4_128_MD5
-TLS_RSA_WITH_3DES_EDE_CBC_SHA
-TLS_RSA_WITH_AES_128_CBC_SHA
-TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA
-TLS_DHE_RSA_WITH_AES_256_CBC_SHA
NOTICE
No algorithms can be selected during generation of encryption keys. SSL v3 is automatically selected for the 
SSL setting according to the application and browser. Do not therefore change the setting manually to SSL 
v2.
Use the following browsers to ensure SSL encryption communication with appropriate strength. Use of any 
of the following browsers achieves SSL encryption communication that ensures confidentiality of the image 
data transmitted and received.
Windows NT4.0, 2000, XP, Server2003, Vista, Server2008, Windows 7
-Recommended is Microsoft Internet Explorer 6 or later.
-Recommended is Netscape Navigator 7.02 or later.

-Recommended is Mozilla Firefox 1.0 or later.
Linux
-Recommended is Netscape Navigator 7.02 or later.
-Recommended is Mozilla Firefox 1.0 or later.
SSL encryption communication with confidentiality properly maintained can be achieved in image data trans-
mitted and received in any of the following applications.
-PageScope Box Operator
-HDD TWAIN
-PageScope Direct Print
-HDD Backup Utility
NOTICE
SSL encryption communication is not applicable to transmission of Secure Print in PageScope Direct Print.
IPP printing
IPP (Internet Printing Protocol) is a function that allows Secure Print Documents and image data stored in 
boxes to be printed via the Internet by using the HTTP (HyperText Transfer Protocol) of the TCP/IP Protocol. 
IPPS (IPP over SSL/TLS) is the type of IPP that performs the SSL encryption communication.

To perform IPP printing, the printer driver must be installed. From Add Printer Wizard, select Connect to 
a printer on the Internet or on a home or office network and type the URL of this machine in the following 
format in the URL field. The printer, for which the settings have been made, can be used in the same manner 
as the ordinary local printer.
http://  /ipp
E.g.: If the machine IP address is 192.168.1.20
Type http://192.168.1.20/ipp
To set IPPS printing:
Type https://  /ipp.

Windows Vista/Server2008, which offers enhanced security functions, gives a certificate error message if the 
SSL certificate is one that is not issued by a certification body. In such cases, it becomes necessary to reg-
ister with Windows Vista the certificate of this machine as that issued by a reliable party for the computer 
account.
First, register Host Name and IP address of this machine in the DNS server in advance. Then, in TCP/IP Set-
tings of PageScope Web Connection, set the DNS Host Name and DNS Default Domain Name registered 
with the DNS server.
It should also be noted that, for the certificate to be imported, a certificate for SSL encryption communication 
should be registered in PageScope Web Connection and exported in advance as the certificate including the 
public key.
